Patent DE-19630697-A1 (DE)
Title: Overcurrent protection device for power semiconducting switch, e.g. MOSFET, IGBT
Inventor: BECKEDAHL PETER
IPC: H03K17/082
Filed: 1996-07-30
Abstract: The monitoring device switches on a forward voltage measurement if a defined gate voltage is exceeded. The voltage measurement is evaluated using a variable switch-off threshold which depends on the gate voltage level. The switch is turned off if an excessive current occurs. The gate voltage is fed to a comparator, a differential amplifier or a transistor which triggers the forward voltage measurement when a defined threshold is reached.

Title: Eddy jet assembly for carpet filament yarns
Inventor: RITTER HELMUT
IPC: D02J1/08
Filed: 1997-01-13
Abstract: The eddy jet assembly, for the production of tangled yarns especially spin texturised filament yarn or carpeting yarn, has an outlet opening for the exhaust air in the initial tangling section between the jet entry and the blown air feed and at a gap from the blown air feed.  This reduces the yarn tension, giving tangling sections asymmetrically in front of and behind the blown air feed.  Also claimed is an operation for continuous working where two eddies are developed in the eddy channel, of different strengths.  The forwards eddy action is stronger than the reverse eddy effect.

Title: Frequency modulated valve control apparatus
Inventor: FRIEDMANN OSWALD
IPC: F15B21/08
Filed: 1997-06-27
Abstract: The valve apparatus (1) comprises a main valving element (5), an auxiliary valve (10) and a control valve (20) controlled by an electronic unit (30) which, via a number of sensors (13a,13b), receives input signals (31a,31b) denoting parameters such as pilot control pressure, fluid temperature, pump flow etc. These parameters determine an output control signal (32) from the electronic unit. In order to minimise hysteresis of a plunger (21), the output control signal is a composite of two component control signals, a first modulated at a relatively high chopper frequency e.g. between 220 to 600 Hz, the other modulated at a lower frequency e.g. between 1/3 and 1/50 of the first frequency, generated and superimposed upon each other by the electronic unit. The lower modulated frequency is regulated so that the valve element and the plunger oscillate, but the plunger does not impact.

Title: Vehicle airbag opening and unfolding mechanism
Inventor: LUTTER GERHARD DIPL ING
IPC: B60R21/26
Filed: 1997-09-26
